Neutrik - NBNC75BDD6X - UHD BNC Rear Twist

Neutrik NBNC75BDD6X rearTWIST UHD BNC 75Ω Connector

The Neutrik NBNC75BDD6X is a professional 75Ω rearTWIST UHD BNC male connector specifically engineered for Ultra High Definition (UHD) video transmission, delivering exceptional performance for 4K, 8K, 12G-SDI and next-generation broadcast systems. Designed with Neutrik's latest connector technology, the NBNC75BDD6X provides outstanding signal integrity, ultra-low return loss, and uncompromising reliability for demanding professional video applications.

Unlike conventional BNC connectors, the UHD series incorporates an optimised centre contact pin and insulator design, significantly reducing return loss at high frequencies. This allows the connector to maintain excellent signal quality across modern UHD workflows while remaining fully compatible with standard 75Ω BNC chassis connectors, making upgrades simple and cost-effective.

Featuring Neutrik's patented rearTWIST® locking system, the connector can be securely connected and disconnected from the rear of the boot rather than the connector body. This makes installation considerably easier in high-density patch panels, recessed bulkheads, OB trucks, equipment racks, and broadcast routing systems where front access is often restricted.

Manufactured using precision Swiss engineering with Antraloy-plated brass components, the NBNC75BDD6X offers exceptional corrosion resistance, durability, and long service life. With a rated lifetime exceeding 1,000 mating cycles, it is built to meet the rigorous demands of professional broadcast, touring, and AV environments.
